Cooling system

This invention relates to motor vehicles and more particularly to an arrangement wherein the engine cooling radiator is mounted in the wall of the body and serves as a closure door for the engine compartment.

` One of the principal objects ofthe invention is to mount :the radiator assembly for outward swinging movement to permit access to the engine through the .inspection opening for adjustment l0 and `replacement of parts, for the replenishment of lubricating oil and other similar purposes.'

A further and important object ofthe invention is to provide Yconduits connecting the engine and radiator in a circuit for the flow of cooling medium which enable relative movement of the radiator without disconnection of couplings or otherwise disturbing the cooling system and contents.

A more complete description of the structure involved will be made with reference to the preferred embodiment of the inventionv as illustrated `in the accompanying drawing wherein Figure l is a side elevation partly broken away o the rear portion of a motor vehicle; Figure 2 is a view looking at the rear wall of the vehicle and Figure 3 is a fragmentary view illustrating `a modification. y

In the drawing the vehicle body I hasa downwardly inclined rear wall in conformity to cur- 30 rent styling and adjacent the rear wall is an en-` closed compartment in winch is mounted the power plant or engine 2 for driving the road wheels 3. The engine illustrated has its cylinders arranged radially of the crankshaft and each cylinder is provided with a cooling jacket, the

several jackets being in communication with each other. The uppermost cylinder jackets are connected through conduits I and 5 with a Y-fltting 8 joined to a tank 1` which is iixedly mounted in the body at the rear wall and adjacent theupper edge of an inspection opening in the wall.- A iiller spout 8 may be associated with the xed tank 1. Closing the rear wall opening is a hinged door .which consists essentially of a-radiato'r assembly, preferably provided with an ornamental grille over its exposed face and a lii't handle 9. The radiator o assembly comprises a cooling core I0 and upper and lower headers orL tanks' II and I2 ilxedly secured on opposite ends ofthe core for communication with the several core tubes. The header I2 at the free end of the swingingassembly is the outlet tank and the header II is the inlettank and is hingdly related to the fixed tank 1. To

y .constitute the hinge and provide for the free 'lo now or coolant between the tanks there are provided on opposite sides a pairof bowed or U- shaped conduits I3, each having one end xed to the header II and the opposite end'pivotally joined to the fixed tank 1 on a transverse axis -which enables the lclosure to be swung from the 5 full line position shown-in Figure 1 to the dotted line position for access tothe engine'. I l The return liquid iiow connection may consist j of a pair of jointed conduits I4 and I5 swivelly joined together at their adjacent ends with their 10 remote ends pivoted, respectively, to the outlet header I2 and to the engine driven pump I6 rigid with the` power plant. The pivotal connections are lsuch-that the tank I2 is in communication with the pump I6 in all relative positions of the radi- 'la ator assembly so that the engine pump circulates u cooling medium through the engine and radiator and the circuit remains intact whether the door is open or closed. s

Advantage istaken of the jointed conduits Il 20 and I5 when in extended position for holding the closure door against accidental closing movement, the conduits serving as anovercenter toggle -v brace and being held against collapse by a pair of complemetary abutment lugs, I1 at the inter--v 25 mediate knucklejoint. l 'For the dissipation of heat absorbed in the engine jacket, air flow through the radiator may be -dependent upon vehicle travel through the provision 'of a tunnel o r duct leading from the '30 front of the vehicle into the engine compartment or optionally a series of air scoops orv louvers I8 may be provided in theI side of the vehicle or other suitable regionl of pressure to direct air into the engine compartment for out- 35 ward flow through the radiator assembly. Alternately an engine'driven fan I9, as seen in Figure 3, may be used to induce air flow or to augment air currents available during car travel.
